   * Keeping the electros hot makes the ESR lower so cheaper ones will do.

   *  It only oozes and dries out anyhow.

   *  Hand soldering? You are joking?

  * If you make them expensive enough no one will want them and then you
don't have to stock them at all - simple.

   * They keep all factory tests brief for obvious reasons - then it becomes
someone else's problem.

   * There is one born every minute, at least and increasing.

 * The head speed is still much higher than the tape speed.

* Policy - voltage spike damage is always the customer's problem.

*  Repairers are a necessary evil - but they are working on that one.
